Sven Kratz was an assistant at the Mobile Interaction Lab of the Department for Informatics of the University of Munich (LMU), Germany, where he obtained his PhD in Computer Science in 2012. From 2008–2011, Sven worked as a researcher and PhD student for Deutsche Telekom Laboratories at the Berlin University of Technology (TU Berlin). Sven completed a 16 week internship in 2010 as well as a 12 week internship in 2011 at the Microsoft Applied Sciences Group in Redmond, WA, USA, where he helped to develop new user interface hardware, experimented with mobile robots and was software developer on the Mayhem team.

Sven’s primary research focus is on sensor-based mobile interfaces that allow for novel types of interaction. This includes gesture recognition, interaction based on distance sensing and pressure, and around-device interaction. Sven also conducts research tabletop applications for mobile devices and associated tracking technologies. Sven received his Diplom degree in Computer Science from RWTH Aachen University in 2007.

In his free time, Sven enjoys playing tennis, sailing and hiking.

Fachliche Dienstleistung

Projekte

PalmSpace

What if mobile phones were equipped with depth imaging cameras? PalmSpace envisions the use of such cameras to facilitate interaction with 3D content using hand gestures. We developed a technique that maps the pose of the user's palm directly to 3D object rotation. Our user study shows that the users could manipulate the 3D objects significantly faster than with a standard virtual trackball on the touch screen. To appear at Advanced Visual Interfaces (AVI) 2012, Capri Island, Italy, May 21-25, 2012.

CapWidgets

The CapWidgets project is an exploration of tangible widgets on mobile devices with capacitive touch screens. Presented as a work-in-progress at CHI 2011 in Vancouver, BC, Canada.

Protractor3D

Protractor3D is a tilt-invariant gesture recognizer for 3D motion gestures from data which can be obtained, for example, from 3D accelerometers on smart phones.

Our public evaluation version has been released as a Python module und GPL v3. We intend to release versions of Protractor3D for iPhone and Android in the near future.
